The Perfect Weather Maps

The problem with the weather is it is always too hot, too cold, too wet or too dry. The solution of course is to adopt a nomadic lifestyle and to migrate around the world using global weather data. To help you plan your annual migratory pattern Perpetual 72 shows you where in the world you can expect a perfect 72 degrees for every month of the year.

Of course 72 degrees Fahrenheit might not be your idea of the perfect temperature,  If that's the case you can use Perfect 72's weather control to set the temperature to any value that you want. Adjust the temperature and the map automatically updates to show where in the world you can expect to find your perfect temperature in every month.

Maps showing the average temperature of different locations for different times of the year can be quite handy. However you might also want to check out how cloudy it might be. Using this global cloud atlas you can find out the average amount of cloud cover that nearly every location on Earth experiences during any month of the year.

EarthEnv's Global 1-km Cloud Cover interactive map visualizes 15 years worth of cloud observations at 1 km resolution. Using the map you can select any month of the year to see how much cloud cover a location experienced over the last fifteen years.

The temperature may not be the only data that you want to consider in your attempts to find the perfect weather. In that case you could use Peter Kerpedjiev's map of annual worldwide weather data. The map uses historical climate data from Wikipedia's city 'weather boxes' to visualize how weather changes during the year around the world.

Using the Sunshine Map it is possible to view the number of hours of sunshine across the globe for every month of the year. The map also allows you to view the changing rates of precipitation, the highest & lowest temperatures and the amount of snowfall.

The map uses Jason Davies' D3 voronoi library to divide the world up into regions based on the closest city with Wikipedia climate data. This does mean that where Wikipedia only has a few cities with climate data.the Voronoi areas are quite large,

The Global Weather Comparison map allows you to compare the weather between different locations around the world. Using the map you can pick two different weather stations, from more than 14,000 locations world-wide, and compare their temperatures, rainfall and hours of sunshine.

To compare the weather between two different locations you just need to click on their markers on the map. The complete annual weather data for these two stations can then be compared in the graph below the map. You can use the map menu to directly compare the temperature, precipitation or sunshine hours between the two locations, in the graph below the map.

If you select a range in the graph at the very bottom of the page you can zoom in on the chosen range in the interactive graph directly above. This Leaflet map also displays a choropleth view of the selected weather variable. The map includes a date control which allows you to select to see a choropleth map for any day from 2005 to 2014.
